[texts]BBC Research and Development Report Number 1969-04
R&D Report 1969-04 : The use of sharp cut-off vestigial sideband filters at television transmitting stations A. Brown An amplitude and group-delay characteristic of the special vestigial sideband filters that may be required at UHF stations working in a channel adjacent to a radio astronomy band is considered, and the effect on transient response assessed. The group-delay errors of the filter, which is assumed to be at the transmitter output terminal, can be satisfactorily corrected by simple al...

R&D Report 1969-14 : Single-sideband transmissions for MF broadcasting: compatibility experiments with conventional receivers K. Hacking A brief investigation has been made into the distortion resulting from the reception of single-sideband and vestigial-sideband signals by an ordinary receiver with an envelope detector. Suitable modulators have been constructed and used to compare systems with different transmission characteristics...

R&D Report 1967-30 : Pulse sound: Suppression of vestigial sideband at 625-line VHF transmitters W. Wharton, J.G. Ingleton If the 405-line television services in Bands I and III were re-engineered for 625-line working whilst maintaining substantially full coverage of the country, it would be necessary to use a closer channel spacing than the 8 MHz spacing available in the UHF bands. The use of pulse sound effects some of the necessary economy in bandwidth, but for a channel spacing of less than ...

R&D Report 1975-29 : A reflection modulator for adding data to a composite television signal at UHF. P. Shelswell A basic reflection modulator cannot be used to add data to a composite television signal at UHF. This report describes the modifications which must be made to a reflection modulator so that it can be used for this purpose. Particular attention is given to the addition of narrowband data to lines in the field-blanking interval...

R&D Report 1986-07 : VSB 2-PSK: a modulation system for digital sound with television. P. Shelswell, A.P. Robinson, R.P. Ritchie, P.R. Durrant This report describes VSB2-PSK, a modulation system suitable for the transmission of digital sound and data associated with a television signal. This modulation system shows good spectral efficiency and little sensitivity to the type of channel imperfections associated with typical television transmissions channels.

R&D Report 1965-43 : Transmission of 625-line television signals in Bands I and III S.M. Edwardson The 625-line transmission standard used in the United Kingdom employs r.f. channels 8 Mc/s wide, which could not be accommodated in the v.h.f. Bands I and III without reducing the number of channels available. Two proposals have been made for modifying the standard to enable the existing 5 Mc/s channels to be used...
